Abstract

An apparatus and method to automate octane number measurements from a knock engine is provided. A first (15) and second (18) reference fuel having different knock octane numbers and a test fuel (20) having an unknown octane number are each provided to the fuel inlet of an engine (29) at a series of flow rates. For each flow rate an average knock intensity is calculated and from the resulting series of average knock intensities, a flow rate which will give a maximum knock intensity is calculated using curve fitting techniques.
